Let's divide 42873036 by 5
The aim is to understand the frequency of 5 in 42873036.

Moving on to step 1:
The number 5 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 5

Step 2:
The number 5 fits into 42 8 times, leaving a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 40 from 42 leaves us with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 5

On to step 3:
5 goes into 28 5 times with a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
The remainder is 3 after subtracting 25 from 28.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 5

On to step 4:
5 can be fit into 37 7 times, resulting in a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 857.0
Subtracting 35 from 37 leaves us with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 5

Moving on to step 5:
5 can be fit into 23 4 times, resulting in a remainder of 3.
The next digit of our result is 4. 
Result so far: 8574.0
Subtracting 20 from 23 leaves us with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 5

Moving on to step 6:
5 goes into 30 6 times with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 85746.0
Subtracting 30 from 30 leaves us with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 5

On to step 7:
5 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 857460.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 5

Advancing to step 8:
If we divide 36 by 5, we get 7 and a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 8574607.0
Subtract 35 from 36 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 9:
10 divided by 5 is 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 8574607.2
Deduct 10 from 10 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
5 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8574607.2
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
The number 5 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 8574607.2
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 8574607.2 with a remaining 0.0.
